There doesn't seem to be a good resource online describing the issues with protocol buffers and deterministic serialization (or lack thereof). This is a collection of links on the subject.

Protocol Buffers v3.0.0. release notes:

The deterministic serialization is, however, NOT canonical across languages; it is also unstable across different builds with schema changes due to unknown fields.

Maps documentation:

Wire format ordering and map iteration ordering of map values is undefined, so you cannot rely on your map items being in a particular order.

#include "noise.h"

float generateNoise(float x, float y, int salt) {
	x = fabs(x);//this function cannot handle negative coordinates, so fabs (floating abs) is required.
	y = fabs(y);//The side effect is that everything is mirrored on the x/y axis :(

	//generate x/y coords for each anchor point around the real point
	int x1 = (int) floor(x);
	int x2 = (int) floor(x) + 1;
	int y1 = (int) floor(y);
